Are you running a bleed off block like a Superaltive ?
And yes an adjustable block is a sorta fix for an over gassed barrel or something like a BRT gas tube . Iv'e just found that personally the combo of an enhanced carrier /A5 buffer tube / green sprinco spring / h2-3 buffer offer the most consistent softest shooter in a sub 11.5 barrel especially if using a Sionics / BRT / Colt fbi hrt or some other barrel with a gas port meant for full power 5.56 loads suppressed at these lengths. Now obviously if your gun is running fine with your adjustable block why waste $$ on more parts , but if starting from scratch this may be a good way to go .
